doa
npo
bid

how is 4:20 pm expressed in military time? *
0420
1620
2020
2120

Explanation:

• For the first question:
• DOA stands for "Dead on Arrival".
• NPO stands for "Nil Per Os" which means nothing by mouth (no food or water).
• BID stands for "twice a day".
• PRN stands for "as needed".
• For the second question:
• To convert from 12 - hour time (pm) to military time (24 - hour time), if the time is in the pm, we add 12 hours to the hour part. For 4:20 pm, \(4 + 12=16\), so it is 1620 in military time.

Answer:

• First question: B. NPO
• Second question: B. 1620
